comment Is there a way to change default order of series in Maple?
Ah, I see now what you mean. It would be better if the popup dialogue that appears when using the right-click menu already was populated with the current value of Order rather than 6. Good idea. For your other question, you can put the command to set Order into your initialization file, so it's done at each startup. See maplesoft.com/support/help/Maple/view.aspx?path=worksheet/…

comment solve complicated system of non-linear equations numerically
What is your working precision (esp, when you "put back this point into the two equations")? Try raising Digits (if only temporarily) before you use subs or eval to do the substitution. Or wrap that check with evalf[d](...) where d is greater than default 10.

comment What's the easiest way to approximate an answer to n places after the decimal?
The point to using displayprecision is that it only affects what is displayed. The values still have their full precision, for any subsequent computation. I only used lprint to demonstrate that fact -- the results of evalf could simply be assigned to names and then used. The special rounding only affects the printing. The earlier approaches using T and Q actually produce specially rounded values (which could also be assigned and used). Your choice.

comment Change of variables in maple
Maple's subs command is a syntactic replacement mechanism, not a mathematical one, and is commonly overused. You might get by using three nested calls to algsubs instead (using your rules one at a time). Ie, algsubs(rule502,algsubs(rule501,algsubs(rule500(...))). Or you could try simplify(...,{rule500,rule501,rule501}) to simplify with side-relations. Please note that your question is not about math and is off-topic here. Better to post it at stackoverflow or mapleprimes.com and also more polite to include your expressions in plaintext Maple syntax for copy & paste.

I've added more detail about M and C. I used Maple 18.01. You haven't yet written which version you're using.
